that the ink sack vis not yproperly and thoroughly Afilled and emptied, this because of tliev'construction ofthe means for compressi ing the' ink sack to expel oldl ink and preventa vacuum: n

V'Another objection to the usual fountain pen of the self-filling type, is that the filling -lever is so located on the side of the pen bar- 4'rel as to be in constant danger of being accil5 dentall'y opened. Also, the opening provided for the filling clip permits the entrance of foreign matter and dirt, which in time finds its way into the'sackchamber, causing trouble in the working parts.

`the ink sack is liable to release ink with Another objectionr to the pens now known is 'that the weight of the pressurebar against the least roughl handling.y Y However, the pen of our invention 1s 1ntended to eliminate many of the 'common objections to the usual self-filling'fountain pen.

Y The penof our invention provides, pril marily, a long. pressure bar, contacting the ink sack for the greater part of its length and width, the lever for emptying and `filling the sack being located at the upper end of the pen barrel, and is protected from movement i and locked in position by a screw cap'.

j, further advantage of theV pen of our in-j ..35

tied, thefpressure barvassumes an angular pop fventionfisthat when the,l sack is being emp- 'sition', Iandlthe rearward-'end of the sack is pressed first, in order that 'no ink will be trapped' inthe rear or upper end ofthe ink .,filling. l A still sack. Likewise, when the penis being filled, thefpressure bar permits the ink to fill the forward Iend of the sack first, leaving no space for air toy enter, insuring rapid andefcient e further advantage 'of the pen of our construction 1s that locking means 'are provided for the pressure bar, when either in an fopen or closed position, thus insuring safety in carrying the pen, as well as casein filling.

The device of our invention comprises ythe usuafpoint 10compfosition` pen holder and plug 11, barrel 12 'and sack 12a. The filling 'device consists of the pressure bar 13, having..- flangeslll, 15 thereona'nd within the pressure bar is a slide baror long link 16, adapted to slide within said pressure bar. Said slide bar is provided with two'sets` of wings,fone set, 17, 18, at the lower end, and a pair 19, 2,0l at the upper end thereof. These four wings 17 18, 19,20 vsuspend the'pressure bar atv four points vand prevent lateral movement thereof. At the upper extremity ofthe pressure bar 13, the flanges 14, 15 are closed byk thevs'top's 21, 22 for a purpose later to be described.v Thelow# er end of saidl slide bar 16, is pivotally secured by a pin 22ab to a shortlink 23, which is pivotally secured to the barrel at its'u-pper end,

`by the pinv23, The upper end of said slide bar 16, is pivotally secured by a pin 211 t-Ofone v V-e'nd of a bell crank 25, said bell crank being pivotally securedto the barrel at 26.,

The upper 'end of he barrel, as is best illustrated in Fig.' 3, is reduced, yand provided with screw threads, for the'receptionof the internally threaded cap,f27. [The purpose of the cap 27 is to cover the bellv crank 2 5, lwhen it is inrv its closed position. L y

In the construction of the device 'above described, care istaken to provide av distance between the stationary pivots 26 and 23a, less than the distance between the movable pivots 22a and V211. lIn this feature lies an important feature ofv ourinvention. By g so arranging bar, showing the stop C bell crank is lifted, thus bringing down V,thepivot 24, sov that the pressure bari13, and slide bar 16, ,carried thereby, assumethe dot,

ted line position shown in Fig. 1.

Thus it is seen that the :rear Vor upperend of the ink sack is depressed first, thus forcing the air and ink out ofthe closed' end 'ofthe sack, preventing a vacuum.

- `When the pressure bar reaches the position shown in Fig. 3,it has reached the limit per-V jn'iittedby the link '23, and further movement upward,l of the bellI crank,l wouldldrawithe pressure bar past its center,`towar`dfthe bell crank, thus'c'ausing abrasion of' thesack, and

` possible injuryto theclo'sedend of 'thesack 'To prevent movement f the pressure bar, the

slide bar is provided, which is permittedto slide inside'of the pressurel bar, when yin the position of F ig, 3. As soon as Vthe link 23 passes beyond a vertical" line through the ticked' position, and remain so until ivot 26, then the parts willy again be in a the bell cranksmove'd downward.

. The stops 19, 2O,V 21, 22 are so positioned u thatv as the bell' crank'is moved tothe position "of Figi' 3, if'the pressure bar is too far for-k l' the sackat'the' pointof engagement thereof no entrapment of air'in the sack. p

`providing thelockin j y scribed is lthat t-he weig t of thev pressure and ward, it" will bepull'ed backward, thus preventing possible injury to the lower'endlof with they hard rubber neck.

vWhen the sackl isbeinglfilled, theforward 7end will be open' in advance'of the closed end,

thus permitting rapid Vand vefficient filling, and

One of thev most= important advantages in slide bar is'lifted and heldofl:I of the sack, so

that, lin moving or striking' the pen thersfack `Will"I'1Ot be'depressd. l

" Thus it is seen that we have providedv a "self fillingfountain pen` that is absolutely efficient, self locking, leak-proof, and dirt-V 'proof Our device has provided all of the' 'advantages of other fountain pens of siinilar type, and has eliminated the usual disad vantages and" shortcomings of such pens, y j o While the illustrations properly disclose our invention, modifications and variations may be madeV withinthe skill of the mechanic "without departure from the spirit of our invention, and we do not wish to be limited except as indicatedin'the appendedlclaims.
